Application filed October 4,. 1926. TSerialllTo Qurinvention relates to improvements in automobile and'truck traction and anti-skid v attachment of which the following is ai specification.

being furnished with thin circular elongated The ob'ect of ourinvention is to provide a combination anti-skid and tractlon device to enable an automobile or truck to travel anywhere over sand, mud, clay, snow or ice,

mobile. or truck. A supplemental disk is turnahly mounted upon an auxiliary hub formed. uponsaidfixed disk; paddles are designed to projectbeyond the face of said drive wheel, andcapable of being withdrawn simultaneously toward the hub, said paddles being pivotallyfmonn'ted near. their centers uponstuds'. fixed to said fixed'dis'k and mechanism for actuating said paddles from the drivers seat, while the vehicle is inmotion or by means of a. socket wrench while at a stand still fronrtheground. Said paddles 1 .arms capable of resilient-contact with a slip- I paddles being shown rojected.

Itj further consists in certain details of construction, all of which will be more fully explained. by referringto the accompanying drawings, in whicl1 g V Fig, 1. is a side elevation of a vehicle iirheel. and our invention secured thereto, the

The paddles 2. are pivotally mounted upon studs 3,. which are fixed to disk A, disk A being fixed to the drive wheel rim at 35. The paddles 2"having bearings 4,

oscillate upon studs '3, the-paddles 2. having knobs 5 adapted to slide "within the slotted holes 6 providedin the disk B. The. disk B is -.t urnably mounted upon the auxiliary. hubq 7,. and gear plate C. havingthe spiralspring I5 and segment ofa pi'nion15 isv also mounted upon said anxiliarvhub The worm gear 8 havingthe bevel pinion -9 mounted upon the wormshaft .10,,is journalled withinjournal boxes 11 'andf12; said journal boxes being fixed to disk A; Elongated :holes. 13 and 1d formedin disk B,..permitidisk.;B',to oscillate :between said journal boxes. The

and. projects through the slotted hole 21 in disk B. The stud '19. also, projectsthrough the slotted hole 22, ir1 the gear plate. C, and

the'cotter pin 20 that passes through-stud 19 secures. the gear plate "C, and disk '13 loosely to disk A. The bevel pinion 9 mount- 7 ed upon the screw pinion-"shaft 10 meshes with the bevel pinionv 235,. the bevel pinion 23 '19 having-a cotter pin 20, is fixed. tov diskA I 'beingfixed to shaft 24 at one of its ends, ,7

and frictionwhe'el 25: being mounted upon its other end. "Saidfhevel pinion 23 being.

in gear with the bevel pinion. 9', transmits amen from the friction wheel. 25 to the worm; gear .8. A tilting gab 26 is pivotally nountedupona standard 27, said standard being clamped to'axle housing of the drive wheel at 28. The tilting gab 26having the curved rails or racks 29' and'3'0 on either side of the friction wheel 25, is capable of being raised and lowered through the medium of the lever 31, the extension rod 34 crank 34 upon shaft 26 and pawl 32 and sector 33 situated near the drivers seat. When the upper rail 29 is loweredinto contact with the periphery of the friction wheel 25, the latter will revolve and project the paddles outwardly, and when the under rail 30 is brought in contact with the friction wheel 25, the latter will reverse and draw the paddies in toward the hub. The shaft 10 ot' the worm gear 8, is square at one of its ends to receive a socket wrench and can be turned in either direction by said socket wrench. Hence the paddles can be projected and retracted and held at any desired position independent of the friction wheel mechanism. Thespiral spring 15 being pressed against block 18 by the action of the worm on gear plate G, thus projects the paddles to their full extent. In turning the gear plate C in the opposite direction, the rod 16 that passes through the block 18, will press the paddles toward the hub; j

The curved arms 36 and the lugs 37 of the paddles 2 are adapted to engage the ground and thus afi'ord increased traction and prevents skidding when the paddles 2 are projected. it

Suitable transmission such as flexible or universal joint shafting may be substituted for the bevel gear transmission, but we prefer the bevel gear as shown.

Having thus described our invention what we claim is: a

1. A combined traction and anti-skid attachment for a vehicle drive wheel comprising a disk having a hub adapted to receive the hub of the drive wheel of an automobile or truck, saiddisk being fixed at its peripheryto the telly of said drive wheel, a supplemental disk rotatably mounted upon an auxiliary hub formed upon said fixed disk and having slots, )addles pivotally mounted upon studs fixed tosaid fixed disk, said paddles having sled like curved arms adapted to come in resilient cont-act withthe ground, and having transverse lugs at their outer ends, knobs fixed at their inner ends, said knobs being designed to slide in said slots and means for rotating said supplemental disk.

2. A combined traction and antiskid attachment for a vehicle drive wheel comprising a disk adapted to be fixed at itsouter periphery to the fellyofsaid drive wheel, said disk having a hub adapted toreceive a gear plate rotatably mounted upon the hub oi? said fixed disk, said gear plate having at rotated in the reverse direction, said worm gear or screw shait being journalled in two boxes mounted upon twostuds fixed upon said fixed disk, said shaft of said screw which projects through said journal boxes being provided with squareends to receive a socket wrench upon either end. j

3. A combined traction and anti-.skidfattaclnnent for a vehicle drive wheel comprising a disk adapted to be fixed at its outerperiphery to the folly of said drive wheel, said disk having a hub adapted to receive the hub of said drive wheel, a supplemental disk rotatably mounted upon the hub of saidfixcd disk, and having slots, paddles pivotally mounted upon studs fixed to said fixed disk, knobs fixed to the inner ends of said paddles designed toslide within the slots in the r0 tatable disk, :1 gear plate rotatably mounted on the hub of said fixed disk, said gear plate having at one end a looselyattached rod' surrounded by a spiral spring and a'segment of a screw pinion at its other end,a block on the rotatable disk having a perforation adapted to receiveone endot' said rod, said spring being interposed between said block and one end of said gear plate to maintain a resilient pressure upon said block,

and a worm gear to actuate said gear plate,

the paddles being projected when the worm gearis rotated in one direction and retracted when the worm gear is rotated in the re-- verse direction, a bevel pinion mounted upon one end of said screw pinion shaft, a corre sponding bevel pinion mounted upon one end oi a horizontal shaft which is journalled in housing fixed upon said disk,a friction wheel mounted upon the other end of said horizontal shaft, said friction wheel being adapted to pass between an upper and lower curved rail attached to a tilting gab mounted upon bearings fixed to the housing of the drive wheel axle, a. reversing leverto raise or lower the said tilting gab through the medium of a connecting rod extending from said lever to a crank fixed tothe tilting gear shaft.
